All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The invention discloses a position determining method, which is applied to electronic equipment, and the flow chart is shown in figure 1, and comprises the following steps:
step S11, establishing a historical position database, wherein the historical position database comprises: position data and base station sequences positioned by the position positioning device;
the historical position database is used for storing the position data positioned by the position positioning device and the base station sequence so as to determine the position data of the position positioning device when the user does not open the position positioning device according to the historical position data.
The position data is a position located by the position locating device, for example: when the position-locating device is a GPS, the position data is a GPS tag, i.e. the geographical position data located by the GPS, such as: specific latitude and longitude or street, etc.; when the position positioning device is a designated wireless network WIFI, the position data is a WIFI position sequence, and the position of the WIFI is determined through the WIFI position sequence, so that the position of a user can be determined. Preferably, the position locating device may be: GPS and specified WIFI.
And the base station sequence refers to the sequence of the base station by the electronic device, such as: the mobile phone obtains the base station sequence, and the base station sequence can determine which base station the user is in, so as to determine the position of the user.
When the historical position database has the position data determined by GPS and/or WIFI and the base station sequence determined by the electronic device,
step S12, when the position locating device is not opened, the current base station sequence is obtained;
in the actual application process, when the position positioning device is not started, the position data determined by the GPS and/or the WIFI cannot be acquired. At this time, no matter whether the position locating device is turned on or not, as long as the electronic device, for example: if the handset is in the on state, the base station sequence can be determined.
Step S13, matching the current base station sequence with the position data in the historical position database to obtain a matching result;
after determining the base station sequence where the user is currently located, querying a historical location database, where the historical location database may be a table, which is a table where location data corresponds to the base station sequence, that is, a base station sequence corresponding to a specific location where the user has been through.
At this time, a historical position database is inquired, position data corresponding to the base station sequence where the user is located currently is searched in the historical position database, and the position data corresponding to the base station sequence is the current position data.
The position data corresponding to the base station sequence may be multiple, for example: under a certain base station, the area covered by the base station is wide, and the corresponding position data may be multiple, at this time, the inquired multiple position data corresponding to the base station sequence is determined as a position range, and the position range is determined as the current position data corresponding to the base station sequence, that is, the range where the current user is located.
And step S14, determining the current position data according to the matching result.
In the location determining method disclosed in this embodiment, a historical location database is established, where the historical location database includes: when the position positioning device is not started, the current base station sequence is obtained, the current base station sequence is matched with the position data in the historical position database to obtain a matching result, and the current position data is determined according to the matching result. According to the scheme, the historical position database is established, and when the position positioning device is not started, the current position corresponding to the current base station sequence is determined according to the historical position data stored in the historical position database, so that the problem that the geographic position of a user cannot be obtained due to the fact that the user does not want to start a GPS sensor for a long time or GPS signals are unstable in the prior art is solved.
The embodiment discloses a position determining method applied to an electronic device, and a flowchart of the method is shown in fig. 2, and includes:
step S21, establishing a historical position database, wherein the historical position database comprises: position data, base station sequence and time information positioned by the position positioning device;
step S22, drawing a time and position curve graph according to the historical position database;
the time information is: when the user holding the electronic device is at a specific location, the time of the user is, for example: in the historical position database, when a user determines a specific position where the user is located through a position positioning device, and when the position data is recorded, the time at the moment, namely the time when the user is at the position, is recorded at the same time; the following steps can be also included: when a user is at a base station, the time of that day.
The time-position curve diagram specifically includes: plotted in days, time on the abscissa and position on the ordinate, and the position may represent: the position data may be: the base station sequence may also be: the position data and the base station sequence are used for obtaining the motion trail of the user every day, so that the motion rule of the user in a day unit is determined. For example: on the weekday, the user goes from home to the unit at 7 am and arrives at 8 am, and goes home from the unit at 6 pm and arrives at 7 am every day. And determining the position of the user at each moment in the working day according to the data.
Step S23, determining first position data of the position of the user holding the electronic equipment in the first time period according to the time-position graph, wherein the position data is larger than a preset probability;
the first position data that the position of the user in the first time period is greater than the predetermined probability, that is, the motion rule with the greater probability of the user can be determined according to the time-position graph, so that the probability of the user in a certain position at a certain moment can be determined to be greater.
For example: taking the above example as an example, at 3 pm on a weekday, the probability of the user in a unit is large; and 8 o' clock at night, the probability that the user is at home is higher.
And it does not meet the situation of larger probability, can be: when the special condition occurs, the user is not in the unit at 3 pm on a business trip day or a holiday, so that the probability of the special condition occurring to the user can be calculated in the historical position database based on the possible special condition, thereby determining the predetermined probability and improving the accuracy of position acquisition.
In addition, the accuracy of determining the position of the user according to the time-position graph is related to the working property of the user or the daily action track of the user. For example: if the user is a college student, the time position graph may be in week units, because the class time and the classroom of each day may be different each week, and thus week units are required.
Further, the unit of hour, or month, or several days may also be used, which is only related to the regularity of the user action track, and is not limited herein.
Step S24, when the position positioning device is not opened, current time information is obtained;
step S25, based on the time-position graph, determines current first position data corresponding to the first time period in which the current time information is located.

step S35, determining current first position data corresponding to a first time period in which current time information is located based on the time-position curve graph, and matching the current base station sequence with the position data in the historical position database to obtain a matching result;
step S36, determining whether the position data in the matching result is consistent with the current first position data;
when the current first location data is determined by the time information and the location data in the matching result is determined by the base station sequence, the current first location data and the location data in the matching result have a high probability of being consistent, and the two different situations may be: late or early, etc.
For example: the position determined by the base station where the user is currently located is a certain subway station at 8 th in the morning and 15 th in the morning, and the user usually reaches the unit at 8 th in the morning and 15 th in the morning according to the time-position curve diagram, and at the moment, the two are inconsistent.
In this case, the position data in the criticizing result is determined as the current position data, subject to the position data in the matching result. Therefore, the position data in the matching result is obtained through the base station sequence, and the base station sequence is the base station sequence of the base station where the electronic equipment held by the user is located currently, and the time effectiveness is achieved; however, the current first position data determined from the time-position graph is obtained from past experience, which is not time-efficient.
Further, in the above case, the base station sequence and the time information corresponding to the base station sequence need to be stored in the historical location database, so as to calculate the probability that the user may be late.
Step S37, if yes, determining the current first position data as the current position data;
and step S38, otherwise, determining the position data in the matching result as the current position data.
Further, when it is required to determine a position of the user at a certain predetermined time before the current time, the method may specifically be:
determining position data of a first moment and a second moment, wherein the first moment is as follows: before and adjacent to the predetermined time, the time at which the position-locating device is in the opened state, the second time being: a time after the predetermined time and adjacent to the predetermined time at which the position locating device is in the opened state; and determining theoretical position data of the preset time according to the time intervals of the first time, the preset time and the second time and the position data of the first time and the second time.
The position positioning device at the first time and the second time is in an open state, for example: the first time is located at (x)1,y1) Second timeThe position of the etching is (x)2,y2) And the position of the user at the preset time needing to be determined, wherein the preset time is a time between a first time and a second time, the first time is a time which is before the preset time and is adjacent to the preset time and has accurate position data, and the second time is a time which is after the preset time and is adjacent to the preset time and has accurate position data.
Then, determining a linear distance between two points, that is, a linear distance between a position of the user at the first time and a position of the user at the second time, and at the same time, determining a time interval between the first time, the predetermined time and the second time, determining an interval proportion, and applying the same proportion to the linear distance according to the interval proportion to determine the position of the predetermined time possibly located, or: the predetermined time is when the user is within a certain range of the location.
In the location determining method disclosed in this embodiment, a historical location database is established, where the historical location database includes: when the position positioning device is not started, the current base station sequence is obtained, the current base station sequence is matched with the position data in the historical position database to obtain a matching result, and the current position data is determined according to the matching result. According to the scheme, the historical position database is established, and when the position positioning device is not started, the current position corresponding to the current base station sequence is determined according to the historical position data stored in the historical position database, so that the problem that the geographic position of a user cannot be obtained due to the fact that the user does not want to start a GPS sensor for a long time or GPS signals are unstable in the prior art is solved.

The position data is a position located by the position locating device, for example: when the position-locating device is a GPS, the position data is a GPS tag, i.e. the geographical position data located by the GPS, such as: specific latitude and longitude or street, etc.; when the position positioning device is a designated wireless network WIFI, the position data is a WIFI position sequence, and the position of the WIFI is determined through the WIFI position sequence, so that the position of a user can be determined. Preferably, the position locating device may be: GPS and specified WIFI.
And the base station sequence refers to the sequence of the base station by the electronic device, such as: the mobile phone obtains the base station sequence, and the base station sequence can determine which base station the user is in, so as to determine the position of the user.
When the historical position database has the position data determined by GPS and/or WIFI and the base station sequence determined by the electronic device,
in the actual application process, when the position positioning device is not started, the position data determined by the GPS and/or the WIFI cannot be acquired. At this time, no matter whether the position locating device is turned on or not, as long as the electronic device, for example: if the handset is in the on state, the base station sequence can be determined.
After determining the base station sequence where the user is currently located, querying a historical location database, where the historical location database may be a table, which is a table where location data corresponds to the base station sequence, that is, a base station sequence corresponding to a specific location where the user has been through.
At this time, a historical position database is inquired, position data corresponding to the base station sequence where the user is located currently is searched in the historical position database, and the position data corresponding to the base station sequence is the current position data.
The position data corresponding to the base station sequence may be multiple, for example: under a certain base station, the area covered by the base station is wide, and the corresponding position data may be multiple, at this time, the inquired multiple position data corresponding to the base station sequence is determined as a position range, and the position range is determined as the current position data corresponding to the base station sequence, that is, the range where the current user is located.

For example: on the weekday, the user goes from home to the unit at 7 am and arrives at 8 am, and goes home from the unit at 6 pm and arrives at 7 am every day. And determining the position of the user at each moment in the working day according to the data.
The first position data that the position of the user in the first time period is greater than the predetermined probability, that is, the motion rule with the greater probability of the user can be determined according to the time-position graph, so that the probability of the user in a certain position at a certain moment can be determined to be greater.
For example: taking the above example as an example, at 3 pm on a weekday, the probability of the user in a unit is large; and 8 o' clock at night, the probability that the user is at home is higher.
And it does not meet the situation of larger probability, can be: when the special condition occurs, the user is not in the unit at 3 pm on a business trip day or a holiday, so that the probability of the special condition occurring to the user can be calculated in the historical position database based on the possible special condition, thereby determining the predetermined probability and improving the accuracy of position acquisition.
In addition, the accuracy of determining the position of the user according to the time-position graph is related to the working property of the user or the daily action track of the user. For example: if the user is a college student, the time position graph may be in week units, because the class time and the classroom of each day may be different each week, and thus week units are required.
Further, the unit of hour, or month, or several days may also be used, which is only related to the regularity of the user action track, and is not limited herein.

For example: the position determined by the base station where the user is currently located is a certain subway station at 8 th in the morning and 15 th in the morning, and the user usually reaches the unit at 8 th in the morning and 15 th in the morning according to the time-position curve diagram, and at the moment, the two are inconsistent.
In this case, the position data in the criticizing result is determined as the current position data, subject to the position data in the matching result. Therefore, the position data in the matching result is obtained through the base station sequence, and the base station sequence is the base station sequence of the base station where the electronic equipment held by the user is located currently, and the time effectiveness is achieved; however, the current first position data determined from the time-position graph is obtained from past experience, which is not time-efficient.
Further, in the above case, the base station sequence and the time information corresponding to the base station sequence need to be stored in the historical location database, so as to calculate the probability that the user may be late.
Further, when it is required to determine a position of the user at a certain predetermined time before the current time, the method may specifically be:
